Sen. John McCain (R-Ariz.) has been diagnosed with brain cancer, the Mayo Clinic Hospital in Phoenix said Wednesday.
The tumor was discovered after the senior Arizona senator underwent a minor procedure last week to remove a blood clot from above his left eye.
“Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot,” the hospital said in a statement.
“The Senator and his family are reviewing further treatment options with his Mayo Clinic care team. Treatment options may include a combination of chemotherapy and radiation.”
McCain’s latest diagnosis is not his first battle with cancer. He underwent a procedure in 2000 to remove a type of skin cancer called melanoma from the left side of his face.
